Answer 1

Answer:

The name of the quadrilateral is rhombus.

Answer 2

Answer:

The name of the quadrilateral is rhombus

Step-by-step explanation:

Given that,

All the four sides of the parallelogram are equal and the adjacent angles of the parallelogram are 120* and 60*.The parallelogram with all equal sides is either a square or an rhombus.

In the parallelogram called square,all the angles in it are equal to 90*.But according to the given question,the adjacent angles in the parallelogram are supposed to be 120* and 60*.Hence,the possibility of the parallelogram being a square is ruled out.hence it must be an rhombus having adjacent angles 120*&60*

Therefore,the name of the quadrilateral is rhombus
